Startup script improvements

- Made the standard and extended startup scripts self-link-aware. This helps
  with deployments that symlink the startup script to more standard
  directories (i.e. /usr/local/bin). readlink is used, which comes
  standard in all Unix-like distributions
- Made the inclusion of a custom sys.config not depend on a custom
  vm.args file. This way you can use a custom sys.config without using
  a custom vm.args file
